Lincoln Center Project page 2 <br /> Pacific and Ben Holt, Stockton. <br /> The inspections on January 26 and 27, 1998 revealed that the boreholes that <br /> were originally placed late in the day and not re-grouted multiple times had <br /> grouts that dropped substantially. Both Levine-Fricke-Recon and Gregg Drilling <br /> crews agreed that late afternoon grouting can create a "dropping" problem and <br /> will take steps in the future to ensure that this problem will not re-occur. It is the <br /> opinion of Mr. Infurna that the CPT boreholes re-grouted on January 26 & 27, <br /> 1998 adequately address the concerns noted in the letter from PHS-EHD dated <br /> January 8, 1998. <br /> Some CPT holes were unable to be located at the Chevron site and may need to <br /> be addressed if they can be located after the stockpiled soil is removed. The <br /> Chevron leaking underground tank site is also under Mr. Infurna's oversight and <br /> he will be watching for indications of any hole-grout problems. <br /> I hope this clears up any grouting concerns that have existed since the CPT <br /> placements. Please contact Mr. Infurna at (209) 468-3454 if you have any <br /> questions or wish to discuss the site. <br /> Donna Heran, REHS, Director <br /> Environmental Health/Division <br /> U <br /> Michael J.
